I call this the "grandpa's keys" problem!
When Grandpa was 20 years old he left the house and forgot to take his keys, so every time he left the house he checked his pockets for his keys.
When he was 24 he left the house and left the stove on. He learned to check the stove before leaving the house.
When he was 28 he left his wallet at home. He learned to check for his wallet.
...
Now Grandpa is 80. His leaving home routine includes: checks for his keys, his phone, his wallet. He ensures the lights are off, the stove is off, the microwave door is closed, the iron is off, the windows are closed in case it rains...
Grandpa has learned from his mistakes so well that it now takes him roughly an hour to leave the house. Also, he finds he doesn't tend to look forward to going out as much as he once did...
